The table below shows the methods of IDiaStackWalkHelper:

Method	Description
IDiaStackWalkHelper::get_registerValue	Retrieves the value of a register.
IDiaStackWalkHelper::put_registerValue	Sets the value of a register.
IDiaStackWalkHelper::readMemory	Reads a block of data from the executable's image in memory.
IDiaStackWalkHelper::searchForReturnAddress	Searches the specified stack frame for the nearest function return address.
IDiaStackWalkHelper::searchForReturnAddressStart	Searches the specified stack frame for a return address at or near the specified stack address.
IDiaStackWalkHelper::frameForVA	Retrieves the stack frame that contains the specified virtual address.
IDiaStackWalkHelper::symbolForVA	Retrieves the symbol that contains the specified virtual address. Note: Symbol must have the type `SymTagFunctionType` (a value from the SymTagEnum Enumeration enumeration).

Remarks

This interface is called by the DIA code to obtain information about the executable to construct a list of stack frames during program execution.

Notes for Callers

A client application implements this interface to support walking the stack during program execution. An instance of this interface is passed to the IDiaStackWalker::getEnumFrames or IDiaStackWalker::getEnumFrames2 methods.
